Supersonic water jets as point-like sources of extremely high pressure

Two interacting supersonic water jets and collisions of a jet with an aluminum target are studied experimentally by hydrodynamic simulations. Supersonic form, when shocks generated underwater electrical explosions conical wire arrays converge. The supplied ∼250 kA, ∼1 μs rise time current pulse. Underwater explosion two placed face to produces propagating in air velocities ∼2.5×103 m/s leading hot plasma formation at temperature ∼2200–3000 K, pressure ∼1.7×1010 Pa, density >1029 m−3. When single array explodes front target, the collision local ∼3×1010 Pa on surface target.
